#1 of top 8 missing features of Galaxy S8: smaller battery

As a reaction to the failure of Galaxy Note 7 battery, Samsung is extremely careful with Galaxy S8 and S8+ battery.

They apparently did not push the design and engineering limit for a bigger battery for S8 and S8+. And if Galaxy S8 battery fails again, Samsung will probably be in the death spiral in smartphone market.

The result is the smaller battery.

It is so small that you should concern about the battery life, although Samsung claimed similar battery life as Galaxy S7.

As a comparison, the 5.8-inch Galaxy S8 has a 3000mAh battery, whose capacity is identical to that ofthe 5.1-inch Galaxy S7.

And the 6.2-inch Galaxy S8+ has a 3500mAh battery, which is even smaller than that (3600mAh) in the 5.5-inch Galaxy S7 edge.

The new 10nm processor may help save some battery. But the screen, which is bigger now, usually is the major battery drainer. There are no new technologies in the Super AMOLED screen for battery saving.
